Physical-layer security in visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2020)
Optical wireless communications (OWC) and its potential to solve physical layer security (PLS) issues are becoming important research areas in 6G communications systems. In this paper, an overview of PLS in visible light ...
Spline Interpolation Based Channel Estimation for ACO-OFDM over Visible Light Channels
(IEEE, 2016)
Visible light communication has been considered one of promising candidate technology to solve performance limitation due to bandwidth shortage at radio frequency (RF) band. In VLC system, the visible light is used not ...
Channel Estimation Using Optical MIMO OFDM Based LED Index Modulation
(IEEE, 2021)
In this paper, a new MIMO channel estimation technique is proposed for generalized LED index modulation (GLIM-OFDM) developed for multi-input multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) based VLC ...
Improved Physical Layer Security in Visible Light Communications by Using Focused Light Emitters
(IEEE, 2021)
A conventional visible light communication system consists of a transmitter, a jammer that includes a few light emitting diodes, a legal listener and an eavesdropper. In this work, a similar system is designed with a ...
Research on Power Distribution Method of OFDM System with Hybrid Energy Supply under Fast Fading Channel
(IEEE, 2021)
An adaptive power allocation by minimizing grid power consumption for the Orthogonal Frequency Division Multiplexing (OFDM) system with the hybrid energy supply under a fast fading channel is proposed in this paper. To ...
